EST = UTC-5 · GMT = UTC±0
Quick Answer
EST is 5 hours behind GMT. Add 5 hours to EST to get GMT.
How to Convert EST to GMT
EST (Eastern Standard Time) is UTC-5, and GMT (Greenwich Mean Time) is UTC±0. To convert EST to GMT, add 5 hours to the EST time. For example, 10:00 AM EST becomes 3:00 PM GMT. If the result exceeds midnight (24:00), the converted time falls on the next day.
EST vs EDT
This converter uses fixed EST (UTC-5). Many locations in the Eastern Time Zone switch to EDT (Eastern Daylight Time, UTC-4) from March to November. During EDT, the offset to GMT is only 4 hours, not 5. If you need automatic EST/EDT detection, use the Eastern Time Now tool.
